... capitalism has been around for 90 years ...

If I have grown 12 cabbages, and you have made four loaves of bread, and I 
swap one of my cabbages for one of your loaves of bread, that's capitalism 
and has been around for as long as humanity has.

If the state owns all the cabbages, and all the bread, and allocates who 
gets what, when, and how, or not, that's socialism and has been around, as 
you say, for 90 years. I give it 10 more years.
